Description
WILLIAM B. BERRY, OF NEW BRIGHTON, PENNSYLVANIA.
BEARING ALLOY.
No Drawing.
- To all whom it may concern:
Be it known that I, WILLIAM D. BERRY, residing at New Brighton, in the county of Beaver and'Stateof Pennsylvania, a citizen of the United States, have invented or discovered a certain new and useful Improvement in Bearin Alloys, of which improvement the following is a specification.
The object of my invention is to provide an alloy for journal bearings for railway car and locomotive axles, rolling-mill roll axles, and in general for axles for all classes of machinery, Which'alloy will for its intended purpose be in every respect equal to the Well known copper-tinlead alloys, but which will contain no tin and hence may be manufactured considerably cheaper than the usual alloys for bearings, the tin being accordingly conserved for other purposes.
My invention is predicated upon-my discovery that, within the relative proportions hereinafter specified, antimony may be combined with copper and lead to forma bearing alloy having the same d sirable characteristics as the well known copper-tin-lead bearing alloys. To these three elements phosphorus may be, and preferably is, added in small proportions as a hardening agent.
The alloy which I provide is essentially a copper base alloy, the percentages of copper and lead depending somewhat upon the requirements for partlcular service conditions. Specifically, the alloy may contain from about 60% to 85% copper, from about 1% to 36% lead, and, depending upon the degree of hardness required, from about 3% to 20% antimony. As an additional hardening agent, and also as a deoxidizer, from about .25 to 3% phosphorus may be added Specification of Letters Patent.

to the alloy. If desired, small quantities of nickel, manganese, silicon or magnesium may be added as a deoxidizing agent or agents.
While, in its broader aspects, my inven tion is unlimited to an alloy of any specific mix within the above stated limits, I have found an, exceptionally desirable alloy to be one comprising about 79% copper, 14% lead, 6% antimony and 1% phosphorus.
In making the alloy, the copper may be first melted in a crucible in the usual mannor, and thereafter the phosphorus, antimony, and lead may be successively added in the same manner in which alloying metals are usually added to obtain the 'most thorough mixing-and alloying of the several elements.
The bearing alloy which I provide is,'as already stated, a copper b'ase alloy in which tin is entirely displaced by relat1vely.large proportions of antimony.
I claim as my invention:
1. A copper base bearing alloy contain ing from about to 85% copper, 1% to 35% lead, and 3% to 20% antimony.
2. A copper base bearing alloy consisting of from about 60% to 20% antimony, and 25% to 3% phosphorus.
3. A copper base bearing alloy consisting In testimony whereof I have hereunto set my handr- WILLIAM D. BERRY. Witnesses:
